Character of the Genus. 
The Movru is form’d of oblong Jaws, and has no Trunk. 
The Weapon at the Tail is fpiral: it is naturally hid; and only 
Females have it. 
They have an ink in Norway, rude, and unciviliz’d, as the coun- 
try in a great meafure is, which excels that of all the world in co- 
lour, clearnefs, and permanency. Some letters, I had the honour to- 
receive from the Bifhop of Bergen, gave me an opportunity of ob- 
fer ving this; and an enquiry into its compofition, produced an Hiftory 
of the fucceeding Fly ; frequent in France and Gerinany, as well as 
there ; and I think not unknown in England: but ’tis with caution 
we muft afcertain the Species of thefe lefler animals. Colour has been: 
taken in as an effential character, but it changes here. 
Our oaks give food and lodging to a multitude of Infe&ts: I think 
there are not lefs than forty-feven creatures of this rank, perfectly 
diftinét in fpecies, and of many Genera, that live in, and on it. 
We fee upon the oak-leaves in our woods in June, round balls, as 
big as nutmegs, green, with a bluth of red, and foft to the touch: 
thefe are the leaf galls with which the Norway ink is made; and 
we have nearly the fame Fly that makes them. They arife from a 
wound made by that Infect, who lays an egg there ; and in their centre 
there is a fmall cavity, within which the Worm lives, that, after a 
time, hatches into this Fly. 
The common galls, with which the common ink is made, and 
which are alfo of fo great ufe in dying, rife from the young fhoots: 
of the oak, not from its leaves; and they are hard and woody. Thefe 
are more numerous; and as they fall with the leaves in Au- 
tumn, they might be collected eafily in great quantity ; and may. 
pethaps be of value, by improving more than one article in Commerce,
